Soil quality is one of the most important factors for sustaining the global biosphere and the basis for sustainable agriculture development. A method for evaluating soil quality changes in time and space at small regional level was developed and used to evaluate the changes of soil quality in Qian Yan Zhou Experimental Station (QYZES) located in subtropical zone in China after 11 year reclamation. The characteristics of soil quality changes in crop land, citrus orchards, pasture, sparse grass land, artificial forests, natural forests, bare land and other land use patterns were analyzed and discussed. Supported with the software of ARC/INFO and FOXBASE, the Qian Yan Zhou Soil Quality Information System (QYZSQIS) was developed. By introducing a concept of relative soil quality index (RSQI), soil quality and its changes were evaluated at the small regional level of QYZES from 1983 to 1994. The study proved that the development of QYZSQIS combining with database of soil changes in various periods was an effective method for evaluating changes of soil quality in time and space at small regional levels, which may be suitable to regional levels, RSQI could serve as uniform criteria making quality levels of regional soils comparative, and ΔRSQI, the changed value of RSQI, was a good standard for the evaluation of soil quality changes. After 11 year reclamation, soils with both very low quality and very high quality were decreased in area, and soil with medium quality obviously increased. As to the land use patterns, soil quality in paddy fields, vegetable fields, and citrus orchards was dominantly improved, however, in fuel woods, sparse grass land, and bare land was mainly degraded. Herb plays an important role in conservation and improvement of soil quality in subtropicalzone in China. The study also shows that soils with higher fertility were degraded more easily. It has the same significance both for improving low quality soils and conserving higher quality soils.

The results show that man made accelerated erosion decreases the numbers of bacteria, fungi and actinomyces, among which fungi was affected drastically. The numbers of cellulose decomposing bacterium, phosphobacteria involving the transformations of C,P decreased rapidly during 3 and 10 years respectively after...

The changes of biological characteristics of soil quality were discussed by comparing micropopulation and soil enzyme activities in forest land and eroded farmland with different years of reclamation. The results show that man made accelerated erosion decreases the numbers of bacteria, fungi and actinomyces, among which fungi was affected drastically. The numbers of cellulose decomposing bacterium, phosphobacteria involving the transformations of C,P decreased rapidly during 3 and 10 years respectively after forest land reclamation,and were sensitive to the changes of eroded environments, and could be treated as microbial indicators of soil quality. The total scores of enzyme activities related to soil fertility factors reduced with increase of reclamation time and erosion intensity, and had an exponential relationship with reclamation year, therefore, the activities of sucrase and alkaline phosphatase could be recommended as enzyme indictors of eroded soil quality.

通过研究比较林地、不同开垦年限的侵蚀农地中微生物区系与土壤酶活性,分析了土壤质量的生物学特性的变化过程。结果表明:人为加速侵蚀主要引起表土层细菌、放线菌、真菌数量减少,其中以真菌下降率最高。参与土壤碳、磷转化的纤维素分解菌、磷细菌分别在林地开垦后的3年、10年出现快速的下降过程,对侵蚀环境反应敏感,可作为反映侵蚀土壤质量变化的微生物指标。随开垦年限和侵蚀强度的增长,与土壤肥力因素相关的酶活性总体水平下降,酶活性总分值与开垦年限呈指数关系,提出用蔗糖酶与碱性磷酸酶的活性作为表征侵蚀土壤质量的酶学指标。

Soil quality comprehensively reflects soil properties and is the most sensitive indicator mirroring dynamic changes of soil condition under the influences of human activities. It is very important for the prevention of soil degradation and the sustainable utilization of soil resources to research the changes of soil quality under the influences of the human activities. The Sanjiang Plain has been built into an important foodstuff base since large area reclamation in 1949. But due to lacking of environmental protection awareness and blindly pursuing economic benefit in the earlier reclamation processes, the soil environment of this area degrades, which will influence the sustainable development of agriculture. This paper establishes soil quality change evaluation model to calculate the soil quality matrixes of the top soils (cultivated layer soil) of the main cultivated soils in the Sanjiang Plain. The Changjing trend of soil quality after large area redamation in the Sanjiang Plain are quantitatively evaluated through analyzing the changes of soil quality indexes of the top soils of the main cultivated soils. Results show the quality indexes of the top soils of the main cultivated soils decrease after large area reclamation. Moreover, with the increment of the cultivation years the indexes decrease more. In the end, the forming reasons of this changing trends is simply discussed.

土壤质量是土壤特性的综合反映,是揭示人类活动影响下的土壤动态变化的最敏感的指标。建立土壤质量变化评价模式,计算三江平原地区主要耕作土壤表层土( 耕作层) 的土壤质量矩阵,利用主要耕作土壤表层土的土壤质量指数的变化来定量地分析三江平原地区大面积开荒后土壤质量的变化趋势。结果表明,大面积开荒后主要耕作土壤的表层土的土壤质量指数均呈下降趋势,土壤发生了明显的退化。最后还探讨了这一变化趋势的形成原因。
